Retro Racing R build

[RetroRacing]

Oh yes, we will be there for the test and tune, im also looking into if there is a proformance type day on Thursday. We want to put as many hours on the car as possible so that we can dial in the handling.

I'm signed up for test/tune on Friday and if the car makes it and is race capable I will run group 4 (as there are fewer BMWs in group 4 than group 1), may need some help from you all !

[Mitch Wright]

Great news and good luck.

[RetroRacing]

We have most of the car back together now, needs a few more days on details and a brake pad install. What class in group 4, we may join you.

We only have two cars coming down, what to hang with us? We will be parking the 48 down by the power poles and have room for 4 cars (we always install 4 tents) so it's a ready set up with compressed air, power, etc.

I will run ITE since ST does not allow tube frames (yet!), I just need to stay in front of the E46 cars, so you will be down near the toilets/cross over bridge ?

[Sgt.Gator]

ORP has club track days Monday and Tuesday that week if you want an unlimited 7 hours of track time. And I'll be at PIR with you Friday-Sunday but without a race car.

[RetroRacing]

SWEET!! Look forward to meeting you both. We will be the big white 48' trailer up against the grass halfway between the dirt road and the toilets.

[RetroRacing]

almost there, diffuser it done and everything is on the car. Going onto scales Saturday, cleaning up some wiring as well, then throwing my 7 back together and we are gtg!

Looking GREAT !!!!

[Hindsight]

I agree it looks fantastic and very intimidating! I like the rear angled bumper exit exhaust.... haven't seen one quite like that yet. I may end up doing something similar.

Hope you have a GoPro!!

[RetroRacing]

Oh yes, we have cameras!

[Mitch Wright]

VERY Nice

[FFRSpec72]

Will you all be running a muffler at all ? I'm running stock exhaust until turbo and then a straight pipe back, not sure that will put me over the 103 db limit or not

[Mitch Wright]

I checked my car with open exhaust when I go karted at our sound station, I was right at 100db at 50ft at 6800rpm

I wonder if 8k will make a difference ?

[Mitch Wright]

It will but the day I was running it was low 50's the cooler temps can be worth +2db. The 100db was not duplicated the other 9 readings were 98.2-98.8. Also cloud cover and low ceiling has an effect. Bob and Michaels car here is 92-93db I believe they are running just a cat.
Our track rules here are 103 @ 50' (SCCA rules) and we require a muffler so I have installed a 12" DynoMax race muffler. In the shop at low RPM it sounds about the same as without the muffler but they always sound louder in the shop.

The 92-93b at NCM was with an OEM up-pipe cat and OEM downpipe cat from our 04FXT donor.
A couple of weeks ago, we tested with a Cobb catless up pipe. I definitely was louder, but we didn't measure at the track.
With our recent engine swap, we are back to OEM set up.

[RetroRacing]

We are running an Aerotech muffler, it's pretty throaty at idle, but we are pretty sure we will be fine at song.

Bob, ditch the up pipe cat asap. When the up pipe cat starts to disintegrate it will take out your turbo. It happens a lot.

Thanks Gator.

Car is done.
Here are a few pics before numbers and such. With all fluids, 22 gal of fuel and a driver, we are at 2190, so about 100lbs more than the 1750 dry that we thought we could do. Still scratching our heads about that, so I'm not happy. Looking at some lighter rims (-40lbs)

[Hindsight]

Excellent! Really looking forward to vid. Is the race this weekend or next?

[Canadian818]

Looks great, nice work with the aero, it'll be glued to the road. Who makes that wrap? It's amazing!

[Mitch Wright]

Guys the car looks fantastic, congratulations.

[Frank818]

Same wrap I'm using, I bought mine from a US seller, but 3M, Avery and all major ones usually have that matte blue available.

[Sgt.Gator]

Great looking car.

[RetroRacing]

3M matte blue, with matte black on the accents. Stay with 3m, or Avery, way easier to work with!

THank you all for the kind words, can't wait to get it on track!!!

[Frank818]

Get it on track? Are you crazy? That's a show car, it cannot roll, too many chances for something to wear out or chip the awesome wrap, powder coat and other neat stuff on.

Get it on track now and tell us about the engine and how fast it goes around the track!

[FFRSpec72]

Will you all have any welding ability with you at the track ? How about alignment ability ? Trying to figure out what I might need to bring

[Sgt.Gator]

Retro has welding. I have SmartStrings I can bring if he doesn't have alignment.

Please bring those if you can, I have caster/camber and turn plates, I'm just not sure how much tweaking this car will require.

[RetroRacing]

So, first of all, with out Tony and Gator, we would not be here today to tell you all, you must have a dry sump to run an R! Running short on time right now, but just wanted you all to know how great both these guys were, helping us out with our multiple teething pains. The car was wonderfull when on track, should be 4 seconds faster next time. Will update tomorrow with some video (I hope).

[Harley818]

Nice work guys, the car looks awesome. Good luck racing, we are looking forward to video.....

Uh Oh..... Motor went I'm guessing.

[Mulry]

Did you get it shut down before it scattered its guts?

[Sgt.Gator]

Did you get it shut down before it scattered its guts?

Yes. No external signs, just awful screeching sounds from inside.

The car is even more impressive in person than the pics. With the new engine and all the little bugs sorted out it's going to be awesome.

Really glad to hear that.

Retro, FWIW there are plenty of ex-NASCAR oil tanks in good to excellent condition on eBay if you want to save a few (or a few hundred) bucks off new. Same with the oil pump, I bought ours that way then sent it in for rebuild/reconfiguration from a 5-stage to a 3-stage (2 suction, one pressure). We're working on a custom pump mount but I think that ARE may have one for sale along with the rest of the kit (pan, pump, mandrels & pulleys) if you want to go that route. Gator, where is that Avaid kit from?

[RetroRacing]

Between Gator and Elements, we have a game plan so thanks. Yes, something inside was screaming to get out, but nothing made any new holes. Here is list of things we need to do:

-reinforce the tube frame at the wing mount...at 5 degrees, it was bending the 1.25 square tubing.
-clearance off the stupid front fender mounts.
-stiffen rear and front spring rate to 700 rear and 500 front. (100lb increase for both)
-install new engine and dry sump
-get more air through the engine compartment (we have a cunning plan..)
-lower the seat another inch. BTW, we are already mounted to the floor bars and are still just 3/4" legal! WTF?
-fix a few mounts for the rear cover and dash cover, stiffen that as well.
-install lsd
-reset ride height.

The car was great, most everything worked as planned. Power on understeer was brutal, but easy to drive around (slower lap times). there was NO oversteer that I could induce, probably both a result of the stupid amount of down force and soft rear springs. The front tire rub really pissed me off, but we will fix.
All and all, a great test.
Uploading video today, will post link. The sound of the car is awesome!

[Sgt.Gator]

Gator, where is that Avaid kit from?

Aviaid - John Schawrtz. http://aviaid.com/ Don't try to buy off the website, call or email John.

He and I have been working on a new design for the pump. The Element Tuning version has the scavenge lines coming in the top and the out the bottom. The problem is the line out the bottom is a pain in the rear to put on and take off if the pump is mounted on the car. And the line has to make a very hard 90 turn and is jammed up on the engine block.

I think the solution is to come in the top and out the side, not the bottom. John has pieced together the parts to make that work. He is shipping me one today. But since I haven't actually test fitted it I can't recommend it yet. If you're not in a big rush let me see how it fits before you order it. And I don't think the mounting plate will work for both a Serp belt- A/C setup (Element) and a mandrel drive (Cosworth and everybody else). We'll probably have to make a mounting plate unless John has one that will work if you want to use the mandrel drive.

You can see in this pic how tight the bottom line is:
